Dark Rangers

The Dark Rangers were a group of villains consisting of Elizabeth Batterby, Brent Cooper, Drake Drew, Jack Landors, and "Dark Black". They originally joined the Alpha Rangers as a separate branch that worked under them but they secretly betrayed the Alpha Rangers and formed their own group when deemed the Alpha Rangers as weak. However, their treachery was discovered.

In their final confrontation, the Dark Rangers initially had the upper hand but were defeated due to the Alpha Rangers's power-ups and were killed in a flash of light.

Their betrayal emotionally wounded the Alpha Rangers, who still feel guilty over being unable to stop their corruption and are still the most powerful enemies ever faced by the Rangers.
